  • Method for treating silicon carbide fibres
    Patent number: 11498877
    Abstract: A method of treating at least one silicon carbide fibre, the method including a) formation of a silica layer at the surface of a silicon carbide fibre having an oxygen content less than or equal to 1% in atomic percentage, the silica layer being formed by contacting this fibre with an oxidizing medium having a temperature greater than or equal to 50° C. and pressure greater than or equal to 1 MPa, and b) removal of the silica layer formed by hydrothermal treatment of the fibre obtained after implementation of step a) in which the fibre is treated with water at a pressure between saturating vapour pressure and 30 MPa and at a temperature less than or equal to 400° C.
    Type: Grant

  • A METHOD OF TREATING SILICON CARBIDE FIBERS
    Publication number: 20180194686
    Abstract: A method of treating at least one silicon carbide fiber, the method including a) putting at least one silicon carbide fiber presenting an oxygen content that is less than or equal to 1% in atomic percentage into contact with an oxidizing medium in order to transform the surface of the fiber chemically and form a surface layer of silica; b) eliminating the resulting silica layer by putting the fiber obtained after performing step a) into contact with an acid liquid medium comprising at least hydrofluoric acid; and c) depositing an interphase layer on the surface of the fiber obtained after performing step b).
